The impact of mining activities in the quality of coastal sea waters

The comparison of the obtained concentration levels with the environmental limits suggests that the quality of the coastal sea water complies with all the requirements imposed by the legislation. Moreover, the majority of the measured parameters appear to have a decreasing temporal trend, reflecting the materialization of significant rehabilitation projects, construction of impermeable disposal sites, etc. The concentrations of dissolved heavy metals exhibited uniformity in the surface and in the bottom of the sea, indicating a minimal impact from the polluted sea sediment.
